PLOW.

SPECIFICATION forming part of Letters Patent No. 634,740, dated October10, 1899.

Application filedllllay 25, 1899- Serial No. 718,184- (No model.)

i To all wnom it may concern:

Be it known that I,-JoHN WILLIA THRUSH, a citizen of the Unit ed States,residing at Keyser,in the county ofMineraland State of West Virginia,have invented certain new and use ful Improvements in Flows; and I dodeclareprovements in plows and cultivators; and the object is to improveand simplify the construction and increase the utility and efficieucy ofthe implement.

To this end the invention consists in certain features of constructionand combination of parts, which will be hereinafter fully described andclaimed.

In the drawings, Figure 1 is a perspective view of m yimproved ploworcultivator. Fig. 2 is a top plan View. Fig. 3 shows one manner ofadjusting theplow. Fig. 4 shows the manner of adjusting the cultivatorfor plowing corn.

In the drawings, ldenotes a clevis having three cars 2, 3, and 4, inwhich the beams 5, 6, and 7, respectively, are pivoted, and this clevisis formed with a slot 8 to receive the coupling-link 9, in which thesingle'or double tree 10 is pivoted. Each beam is provided with astandard 12, the lower endof which carries the usual shovel-point 13.

14 14: denote X-shaped braces connecting the standards, the outer onesand the bottom part of the central one being provided with eyebolts 1515 to receive the contiguous ends of the braces 14, the inner upper endsof which are journaled in a slotted bracket 16, having a slidingengagement with the central standard bymeans of the screw-bolts 17 17.

18 denotes a U-shaped bracket fixed to the central beam to receive theforward ends of the handle-bars 19 19, which are supported on thecenterstandard by the transverse brace 20 and the V-shaped brace 21. 'Asecond V- shaped brace 22 also connects the handles with the centerbeam, and the upper ends of this latter brace terminate in lateral ears23 23, which rest upon suitable angle-brackets 24. 24:, fixed to theoutside standards.

.2525 denote lateral bracket-arms fixed to the, opposite sides of thecentral beam and which alternately engage the guard-shoes 26 26, fixedto the inside face of both of the outside beams, as shown, and whichserve as guards for the forward ends of the beams. The upper ends of theoutside standards are formed with notches 27 27 to receive thehandistanceto the rear, so that when plowing v corn the two outsideshovel-points form a furrow near the corn-row and the rear shovelpointsplits the center.

. It will of course be understood that various changes in theform,proportion,and the minor 'details of construction may be resortedto Without departing from the spirit or sacrificing any of theadvantages of this invention.

Having thus described the invention, what is claimed, and desired tobesecured by Letters Pate nt,,is

A plow comprising a clevis, the three plowbeams pivoted thereto, andprovided with the standards and shovel-points, the X-shaped bracesconnecting said standards, the handles attached to the center beam andstandard, and means for locking the beams in advance of each other,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN WILLIAM THRUSH.
